It looks like fprint_w is broken for systems where HOST_WIDE_INT is 'long long'
and that type is longer then type 'long'.

Inside fprint_w we call sprint_ul_rev and that function is defined to take a 
'unsigned long' argument instead of a 'long long' argument which can cause a
truncation of the incoming value that we are trying to print.

I am testing this patch to see if it fixes all the problems.
